PayPal: OpenStack Won't Replace VMware In Data Center

VMware vs. OpenStack won’t be an either/or decision for PayPal. It will layer OpenStack on top of existing tech as it moves toward a software-defined data center.

20 Great Ideas To Steal In 2013

PayPal is on a mission to remake its data center. It's taking it from a typical enterprise-style operation to a more agile, flexible one to better compete in offering payment methods on the Web.

Exactly what it's doing in its data centers remains somewhat under wraps. PayPal isn't eager to disclose too many details of its software infrastructure or its operations. But one thing is clear. Even though it's an implementer of OpenStack cloud software, it's still relying on VMware for core virtualization services.

That was a flaming topic in the news last March, as Business Insider and Forbes, among others, reported that PayPal was moving away from use of VMware in its data centers to OpenStack, replacing the one with the other. At that time PayPal had implemented OpenStack as a pilot project on three servers. Over the intervening six months, it has expanded its use to many more. OpenStack-equipped servers now handle about 20% of PayPal's payment processing traffic.

"We are not moving away from VMware," said Nat Rajesh Natarajan, VP of platform engineering and operations, in a recent interview. "We are leveraging our investment in VMware as we grow our capacity with OpenStack."

PayPal likes the ability to manage virtualized resources through VMware's vSphere 5 and the vCenter management console. It also likes the speedy end user provisioning and potential storage and network virtualization provided through OpenStack. OpenStack offers the KVM hypervisor by default, but PayPal will continue to use its ESX Server virtual machines. They run under the OpenStack cloud software as well.

Reading between the lines, PayPal layers OpenStack on top of its virtual environment and gets the end user self-provisioning and total resource orchestration that it's seeking. It's avoiding too much dependence on a single vendor, even though it likes that vendor's core product line. And it's giving itself breathing room to establish what may be a more flexible infrastructure for the future. That means finding APIs that are not proprietary that its developers may use to access fundamental services. OpenStack provides those APIs.

It's not a knock on VMware that PayPal has adopted this route. But implicit is a wariness and acknowledgement of how dependent their IT infrastructure could become on VMware, if PayPal merely follows VMware's lead into cloud computing. It's both a testament to the job VMware has done in virtualizing the data center and the challenge it faces in convincing the enterprise customers already in its grip that they should follow it straight into the cloud.

At the same time, Natarajan said VMware will remain its principal virtualization vendor; it has not deployed Microsoft's Hyper-V, even though it comes free with Windows Server.

"We are trying to get back to our roots. We are a startup technology company at heart and we're trying again to push the edges of what can be done," said Natarajan.

At the recent CloudBeat show in San Francisco, Saran Mandair, PayPal's senior director of platform engineering and operations, sat down to explain PayPal's OpenStack initiative in greater depth. He ticked off the immediate objectives: give developers the resources they need quickly "so they don't have to worry about IT provisioning" and gain an ability to "implement and deploy a new service quickly."

These comments speak to the sense of competition that now hovers over established electronic payment system vendors as newcomers seem to pop up every other week. In words that echoed Natarajan's, Mandair said the move to implement OpenStack reflected PayPal's need "to ensure we have the engineering muscle internally" to control its own future.

re: PayPal: OpenStack Won't Replace VMware In Data Center

PayPal represents the long term challenge posed by OpenStack to VMware. If it works as advertised and grows more sophisticated, OpenStack adopters will be able to draw a line in the sand for VMware: up to here, to the edge of the cloud, and no further,

Vendor captivity is a very real challenge for all businesses. Businesses should avoid vendor lock-in as well as aged, legacy and proprietary technologies.The OpenStack framework is a viable alternative for highly skilled enterprises that maintain software development and programming skills. These organizations run the risk of focusing their captivity from the vendor to the programmers and engineers who built the OpenStack environment. Furthermore, why would an organization focus these talented people on commoditized infrastructure initiatives rather than business value adding projects.
